Since 2021, the EWUU alliance has organized CBL challenges for third-year bachelor students and master students from TU/e, WUR, UU and UMC Utrecht. Below are some examples of these courses.

• COVID Challenge
  The Covid-19 pandemic confronted us with a new reality. For the Covid Challenge, the municipality of Utrecht was looking for solutions to minimize the health, social, and economic burden of the pandemic for Utrecht residents. Student teams set to work, in line with the national corona measures, to find creative solutions.

• Dutch Dairy Challenge
  The Dutch Dairy Challenge helped dairy farmers to give ‘hands and feet’ to their own innovative and entrepreneurial idea for the future of the dairy farm. Students joined the team of a dairy farmer and together with a professional coach, the students developed entrepreneurial and start-up skills.

• Food for Health and Safety Challenge
  The Ministry of Defense was looking for a new food concept for soldiers on training and missions. In this challenge, students were challenged to design a new sustainable concept that satisfied the military while meeting all the requirements of the ministry.

• Inter-University Sustainability Challenge
  What will the sustainable city of the future look like and how can we achieve sustainable cities? Within this challenge, the students were given a choice of three subjects: (1) Urban agriculture, (2) Air quality, or (3) Energy transition. In interdisciplinary teams, they worked together, each with their own expertise, on out-of-the-box, scientific solutions for the U.N. Sustainable Development Goals (SDGs).

• Bio-med-tech Interdisciplinary Team Training (BITT)
  In this challenge a current and urgent problem of a patient was the starting point. Think of risks due to adhesions as a result of multiple heart operations and an eating problem due to tumor treatment. Three small groups of students from different institutions and multiple disciplines worked on a solution for these patients.
  
• RAT Challenge
  In this challenge a group of students and professionals found solutions in a multidisciplinary context for the complex problem of animal testing.\

• The Waddenzee Summerlab
  This course was focused on broadening, deepening, enriching, and connecting topics related to the Waddenzee. It was tailored to students’ studies or specific interests. By bridging, bonding, and creating crossovers in various disciplines, the course aimed to open up new and unforeseen perspectives for all participants. Students, organized in multidisciplinary and multi-institutional groups, designed and led the workshops, with teachers remaining in the background.
• The Regenerative City
  This challenge offered an approach to regenerative development. It provided the tools and frameworks to navigate play-based work and offered a regenerative leadership approach for change. Participants worked with local stakeholders, experts, and the land itself. They gave voice to this place, explored its potential, and helped maintain, restore, and regenerate the community, local economy, and nature. The students camped on site (Scheg van West—an ecological corridor leading into the city of Amsterdam).
  
• Planetary Health and Climate Resilient Health Systems Challenge
  In this challenge students gained an in-depth understanding of the complexities and possible trade-offs necessary to build health systems supportive of both human and environmental health and respond effectively to climate change. The course had a combination of online modules, in-class workshops and interactive (international) online seminars.
  Planetary Health is about hoe to identify new pathways that will support the renewed relationship between humans and Earth’s natural systems – in a way that society can continue to responding to their needs without overburdening their environment and the Earth’s natural systems.
